Schema creation APIs in Go ​

For v1.4.4, node and relationship full-text indexes use one schema mutation:

go
err := schema.AddFulltextIndex("documents", []string{"Document"},
    []string{"title", "body"}, storage.ConstraintEntityNode)

err = schema.AddFulltextIndex("links", []string{"LINKS_TO"},
    []string{"note"}, storage.ConstraintEntityRelationship)

Migrate former three-argument AddFulltextIndex calls by supplying ConstraintEntityNode. Replace AddFulltextRelationshipIndex calls with AddFulltextIndex and supply ConstraintEntityRelationship.

The schema owns the supplied target and property slices. An existing name is an idempotent no-op, including a collision with an index of the other entity kind. Invalid entity kinds return ErrInvalidData without persisting or publishing an index. Persistence failures retain the previous schema.

Cypher syntax, index definitions, Badger keys, stored payloads and the storage version are unchanged; this Go API migration needs no database migration.

Vector and property-type creation ​

Go callers now select vector entity scope directly with schema.AddVectorIndex(name, labelOrType, property, dimensions, similarity, entityType). The node-only forwarding form and AddVectorIndexForEntity are retired; use storage.ConstraintEntityNode or storage.ConstraintEntityRelationship explicitly.

Property-type creation uses schema.AddPropertyTypeConstraint(name, labelOrType, property, expectedType, opts), where opts is storage.PropertyTypeConstraintOptions. Move an earlier optional entity argument into opts.EntityType; set opts.IfNotExists when required. The separate AddPropertyTypeConstraintWithOptions entry point is retired. For example:

go
err := schema.AddPropertyTypeConstraint("person_age", "Person", "age",
    storage.PropertyTypeInteger, storage.PropertyTypeConstraintOptions{
        EntityType: storage.ConstraintEntityNode,
        IfNotExists: true,
    })

These changes migrate Go call sites to one implementation for each operation. Cypher and protocol syntax, existing persisted definitions and storage formats are unchanged.
